I'm looking at purchasing a B-Stock Threatcon-2 12" and have a question. I have an Alipine PDX-F4 100x4 watt amplifier. I am running 100x2 watts to my front and am going to bridge the rear channels to 200 watts. The amp is 2/3/4 ohm stable in regular & bridged mode. Is it better for me to get the 2 ohm DVC and run a 4 ohm load to the amp or the 4 ohm DVC and run a 2 ohm load to the amp? It's only a $10 difference but I am curious as to what is most beneficial to my system. Thanks for your help!
